OverviewNCBI Gene

Members of the LY6 protein family (see SLURP1; MIM 606119), such as LYPD6, have at least one 80-amino acid LU domain that contains 10 conserved cysteines with a defined disulfide-bonding pattern (Zhang et al., 2010 [PubMed 19653121]).[supplied by OMIM, Apr 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LYPD6 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads LYPD6 as an antibody target. Whether an autoantibody or antibody against LYPD6 could matter depends on whether native LYPD6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LYPD6 is annotated at the cell surface, where native LYPD6 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.

Annotation status

The present source text does not explicitly label LYPD6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
